WALDEMAR GROTHE, OF BERLIN, GERMANY.

ADJUSTABLE TYPE-FOUNDING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 501,934, dated J u1y25, 1893. Application filed April 14, 1892. Serial No. 429,239. (110model.) Patented in Germany September 12, 1891, No- 62,787.

To all whom it may concern.-

Be it known that I, WALDEMAR GROTHE, a subject of the Emperor ofGermany, residing at the city of Berlin, Germany, have in- 5 Ventedcertain new and useful Improvements in Adjustable Type-FoundingApparatus, (for which Iobtained German Letters Patent No.

62,787,015 September 12, 1891,) of which the following is aspecification.

Inpractice it frequently happens that the compositors set up all thetype of a particular letter or character contained in the fonts of typebelonging to aprinting establishment, and under such circumstances itbecomes necessary to obtain additional fonts of type from the typefounder in order to supply such deficiency thus entailing loss of timeand incurring expense.

The principal objects of my present invention are first, to provide asimple, durable, reliable and comparatively inexpensive apparatusadapted for use by compositors, printers and others as a means forfounding or casting types; and second, to construct and arrange theparts of such type founding apparatus in such manner that the same maybe employed for casting or founding types of any required size.

My invention consists of a type founding device comprising a pair ofpivotal levers pro: vided respectively with jaws having adj ustable endand pivotal side plates and one of themprovided with a pour hole orgate.

My invention further consists of a type founding device comprising apair of pivotal levers provided respectively with jaws having adjustableend plates and pivotal side plates; and my invention further consists ofthe improvements in type founding devices hereinafter described andclaimed.

The nature, characteristic features and scope of my invention will bemore fully understood from the following'description taken in connectionwith the accompanying draw- 5 ings forming part hereof; and in Which-Figure 1, is a perspective view of an adjustable type founding deviceembodying features of my invention and showing the jaws and one of theside plates in open position,

and also showing the parts of the device arranged to make the largesttype. Fig.2, is a front view of the upper portion of the deviceillustrated in Fig. 1, showing. the jaws and side plate in closedposition and also showing the gate or pour-holeof the mold. Fig. 3, is arear view of the upper portion of the device illustrated in Fig. 1,showing a catch for normally maintaining the other side plate in closedposition. Fig. 5, is a front view of the device illustrated in Fig. 1,showing the side plate thereof broken away and also showing the parts inposition for making the smallest type; and Fig. 4., is a sectional viewtaken on the line ;1 of Fig. 2, and illustrating a space for thereception of the papier-mach that constitutes the matrix.

In the drawings a and b, are hand-levers pivoted together as at c, andprovided with bifurcated upperv extremities a and b, to which the jaws dand e are pivotally connected by means of bolts and nuts (1' and e.

f and g, are end plates provided with oblong slots, Figs. 1 and 2, forthe reception of binding-screws f and g, suitably connected with thejaws d and e, so that the end plates f and 9, may be shifted endwise inrespect to the jaws d and e, for purposes hereinafter explained and thenclamped to place by means of bindingscrews f and g.

k, is a side-plate pivoted as at to the jaw 01, and provided with apour-hole or gate 10 having sharp edges and with an eye 763, forpurposes to be presently described.

Z, is another side-plate pivotally connected with the jaw 01, by meansof a hinge Z, as illustrated in Fig. 3.

Z is a latch or button for maintaining the plate Z, normally in closedposition and for permitting the same to be opened. The edges of the jawsd and e, are beveled oif as at m, Fig. 4, in order to form a space forthe reception of the mass of papier-mach m, or other analogous materialthat is employed as the matrix.

The mode of operation of the hereinabove described device, is asfollows:-The type constituting the pattern, for example, the type mshown by dotted lines in Fig.1,is inserted between the jaws d, and e,and the end plates g and f, whereupon the Working faces of the jaws dand e, are fitted to the sides of the type m by means of the set-screwsf and g, and by turning the jaws about their pivots e and '01. Thesejaws are then clamped to the levers a and b,by means of the bolts andnuts d and e, and the end plates g and f, are clamped to the jaws bymeans of the setscrewsf' and g. Thepattern type m is then removed andamass of papier-mach m, Fig. 1, is applied to the side-plate I, and isheld to place by means of the beveled edges m, of the jaws asillustrated in Fig. 4:. An impression of the character of the patterntype m is then obtained in the papier-mach m, whereupon the device isclosed, as illustrated in Fig. 2, and the interior space or moldincluded by the ends of the jaws d and e, the end plates g and f, theside plate is, and the papier-mach matrix m, is filled with melted typemetal that is introduced through the gate or pourhole 70 After themolten type metal has set the side-plate 7c, is opened by meansof a rod,not shown, that may be inserted in the eye k Duringt-his operation thesharp edge of the gate 70 severs the metal that may have cooled therein,or in other words, the lug from the cast type. The finished type maythen be removed from the mold by slightly opening the jaws d and e, andpermitting it to fall out. The repetition of the hereinbefore describedoperation results in the production of similar type. Whenever it becomesnecessary or desirable to remove the papiermach matrix 'm, the button orlatch 1 is turned to one side and the side-plate Z, is 1 opened aroundits hinge Z, whereupon the matrixm, may be readily removed from thedevice.

Having thus described the nature and objects of my invention, what Iclaim as new, 1

and desire to secure by Letters Patent, is

1. A type founding device, comprising a pair of pivotal levers providedwith jaws having adjustable end plates and pivotal side plates and oneof them provided with a pour poses set forth.

2. A type founding device, comprising a pair of pivotal-levers providedwith pivotal jaws having adjustable end-plates and a pair ofside-plates, whereof one is pivotally supported and provided withapour-hole or gate, substantially as and forthe purposes set forth.

3. A type founding device, comprising a pair of pivotal levers providedwith pivotal jaws having adjustable end-plates, a pivotal side-platehaving a gateor pou r-hole, a hinged side-plate for supporting a matrix,and a button or latch for engaging the hinged sideplate, substantiallyas and for the purposes set forth. 7 l 4:. A type founding devicecomprising a pair of pivotallevers provided with jaws having end-platesand beveled edges, a side'plate hinged to one of said jaws andconstituting with the beveled edges of the jaws a support for a matrix,means for maintaining said sideplate in closed position, and a secondsideplate pivoted to one of said jaws and provided with a pour-hole orgate, substantially as and for the purposes set forth.

In witness whereof I have hereunto signed 1 my name in the presence oftwo subscribing witnesses.
